Yeah, okay, you're right, domain knowledge is important. I still think a clear and insightful description of practical experience is more important, though.

I don't see what's factually incorrect in this article. The author says that the tether is kind of a pain, and the fact that the Gear is tether-free makes it more compelling (even though it's weaker in other aspects). That's opinion -- useful opinion! The basic facts (tethered versus untethered) seem correct.
